Title: Carrying unit of copying device
Inventor: OKANO TAKESHI
IPC: B65H29/52
Filed: 1979-07-18
Abstract: PURPOSE: To prevent generation of transverse slippage difference and prevent attraction creases, by providing fixed guide members between the feeding position of the photosensitive material and the carrying drum to slide the photosensitive material.  
     CONSTITUTION: Carrying unit 10 is formed by cylindrical fixed guides 18 and 19 and carrying drum 5. Photosensitive material 8 is attracted electrostatically by carrying drum 5 which has been charged and is carried by rotation of carrying drum 5. Since photosensitive material 8 is wound along curved surfaces of fixed guides 18 and 19, photosensitive material 8 slides while receiving frictional force in the contact face to fixed guides 18 and 19. Therefore, photosensitive material 8 can be prevented from generating transverse slippage gradually due to deflection of the parallel degree of fixed guides 18 and 19. Further, tensile force applied to photosensitive material 8 can be selected by selecting the winding angle for fixed guides 18 and 19, so that attraction creases of photosensitive material 8 can be prevented.

Title: Apparatus for cutting recording roll paper for electrostatic plotter
Inventor: AIZAWA TOKUJI
IPC: B26D7/06
Filed: 1986-04-18
Abstract: PURPOSE:To cut recording roll paper with high accuracy by always stabilizing the feed-in of the recording roll paper, by a method wherein a freely rotatable press roller for contacting the recording roll paper with a drive roller under predetermined pressure is formed of a sponge like material. CONSTITUTION:A press roller 9 feeding recording roll paper 3 while grasping the upper and lower parts thereof along with a feed-in roller 6 is formed of a sponge like material elastically deformed by the pressure contact with the recording roll paper 3 so as to follow the shape of the pressure contact surface of the roll paper 3. Because of this, even when the interval between the feed-in roller 6 and each press roller 9 is different by a mount error or the roller 6 has no out-of-roundness shape and the interval between both rollers 6, 9 changes cyclically, the roller 9 easily and elastically deforms so as to follow said change. Therefore, the grasping force of the recording roll paper does not almost change. As a result, trouble such that the feed speed of the recording roll paper 3 becomes unstable or the recording roll paper 3 meanders is not generated and the recording roll paper 3 can be cut with high accuracy.

Filed: 1988-04-13
Abstract: PURPOSE:To measure a dew point stably and accurately for a long period by providing an optical fiber for projection which guides light from a light source to a dew condensation part and an optical fiber for projection which guides light from the dew condensation part to an optical sensor. CONSTITUTION:The refrigerant of a refrigerating circuit 70 that a thermostatic humidistat 7 is normally equipped with is utilized and part of the low- temperature refrigerant which is insulated thermally and expanded by an expanding mechanism 72 is supplied to a cooling part 4 to cool the dew condensation part 1. Further, the temperature of the dew condensation part 1 is controlled by a heater 3. When the temperature of the dew condensation part 1 is lowered by stopping the heater 3 or decreasing its output, drops of dew are generated on the dew condensation part 1, and consequently the quantity of light which is projected from the optical fiber 5 for projection and reaches the optical fiber 6 for photodetection decreases and the optical sensor 9 detects that to detect the dewing. At this time, the temperature of the dew condensation part 1 is detected by a temperature sensor as a dew point. Consequently, the dew point measurement which is stable and accurate for a long period is enabled.

IPC: B60R16/02
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of an on-vehicle control device to perform operational control of on-vehicle electric equipment on the basis of different car conditions. SOLUTION: From a battery, power is supplied at all times to a controller 11 of an on-board control device 4. When there is no need to operate electric equipment 13, the normal processing for operational control of the electric equipment 13 by the controller 11 on the basis of different car conditions is stopped and thereby power saving is carried out. Thus the power consumption of the controller 11 is reduced. When a need to operate the electric fittings 13 arises, the power saving mode is disengaged, and it is made practicable so that the controller 13 is restituted to the normal processing condition immediately.

Title: Optical rotary encoder
Inventor: ATOMACHI TOSHIAKI
IPC: H03M1/24
Filed: 1988-04-13
Abstract: PURPOSE:To reduce the size of the device and to improve the environmental resistance and durability by making an LED current constant with the drain current of an FET. CONSTITUTION:Light emitted by an LED 1 is photodetected by a photodiode 2 which is closed and opened with slit plates 3 and 4 and converted into a current signal. The distance between the LED 1 and photodiode 2 is set to 1-4mm and the low level of the current IF of the LED 1 is compensated to obtain a necessary current gain. Then a stop 5 is provided to a lens surface and its aperture rate is set to 15-30%, thereby cutting off scattered light at the outer periphery of a lens. Consequently, the current IF of the LED 1 is determined by the current Id of an FET 8, whose gate is short-circuited to GND, so the current IF becomes maximum to enter the state of a current Idss, so that the current IF of the FET 8 is equal to the current Idss of the LED 1. Therefore, the currents of LEDs which are connected in series can be made constant by one FET and a stable signal is obtained.

Abstract: PURPOSE:To suppress the inutile electric-power consumption when the diagnosed parts are in normal state by supplying the back-up electric current into the memory part of a diganostic circuit after engine stop only when anomaly is generated in the diagnosed parts, in the captioned apparatus. CONSTITUTION:When a diagnostic circuit 2 judges the trouble of diagnosed parts 1a-1d, the result is memorized into a RAM3, and H signal is input into a transistor 13 from the diagnostic circuit 2, and the transistor 13 is turned ON, and the gate voltage of an N-gate thyristor 11 becomes below a prescribed value, and the N-gate thyristor 11 is brought into conduction. Therefore, the trouble contents memorized in the RAM3 is held after engine stop, too. When the diagnosed parts 1a-1d are in normal state, L signal is input into the transistor 13 from the diagnostic circuit 2, and since the transistor 13 is in OFF state, the gate voltage of the N-gate thyristor 11 becomes over a prescribed value, and the N-gate thyristor 11 is maintained in nonconduction state, and the electric conduction from a battery 7 to the RAM3 is cut-off.
